Some observations have 79% of observations missing. What’s going on with these? I’m only showing rows with greater than 25% missing. It’s somewhat arbitrary but to not have data for a fourth of the survey seems odd.

4.2 Matches with previous rounds

#table(yt$sample_id %in% unique(fieldDat$sample_id))

Through September 14, 2017 we have one soil sample id in round 2 that doesn’t exist in previous rounds. It is sample_id 1437, 1300.

What is up with that observation?

4.3 Completion rates

baseComplete <- fieldDat %>%
  filter(season =="15b") %>%
  dplyr::select(sample_id) 
compB <- round(prop.table(table(baseComplete$sample_id %in% yt$sample_id)),2)
r1Complete <- fieldDat %>%
  filter(season =="16b") %>%
  dplyr::select(sample_id) 
compR1 <- round(prop.table(table(r1Complete$sample_id %in% yt$sample_id)),2)

Through September 14, 2017 we’ve found 99% of baseline farmers. We have 26 to go.

Through September 14, 2017 we’ve found 99% of round 1 farmers. We have 25 to go.

As we get closer to the end of enumeration I will produce a report of sample_ids that have not yet been surveyed so we can understand precisely why some farmers were not found again.

4.4 Attrition summary

# code to check merge match before match is performed
# the code should show you how many overlaps you have in your merge variable
# and a summary of the values that don't match
# tested using ke_round_1_py
vecFiller <- function(vec){
  vec[2] = ifelse(is.na(vec[2]), 0, vec[2])
  return(vec)
}
mergeReport <- function(master, using){
  
  # dat1 into dat2
  
  c1 <- vecFiller(table(master %in% using))
  c2 <- vecFiller(table(using %in% master))
  
  notMatch1 <- master[!master %in% using]
  notMatch2 <- using[!using %in% master]
  
  tab <- data.frame(rbind(c1, c2))
  rownames(tab) <- c("Master in Using", "Using in Master")
  
  outList <- list(tab, notMatch1, notMatch2)
  names(outList) <- c("matching.table", "missing.from.using", "missing.from.master")
  
  return(
    outList
  )
  
  
}
attReport <- mergeReport(baseComplete$sample_id, yt$sample_id)

We currently have 26 more surveys to complete from the baseline. The complete list of missing farmer ids will be shared once we’re down to a more reasonable number.

4.4.1 Attrition farmer list

attOut is the list of baseline farmers not found during the second survey round. attReport are those farmers that are missing

attOut <- fieldDat %>%
  filter(season =="15b") %>%
  filter(sample_id %in% attReport$missing.from.using) %>%
  dplyr::select(sample_id, district, village)
#load the baseline data
load("../rw_round_1/rawBaselineWithIdentifers.Rdata")
attritionTab <- d %>% 
  dplyr::select(district, selected_cell, umudugudu,  sample_id, farmer_name) %>%
  mutate(sample_id = tolower(sample_id), # because we're makring those not found
         found = ifelse(sample_id %in% attOut$sample_id, FALSE, TRUE)) %>%
  left_join(., ytwo[, c("x18a.farmer.name", "x18b.name.of.the.respondent", "x19a.farmer.phone.number", "x.form.sample_id",
                        "x20.in.case.we.can.not.reach.the.client.directly..please.provide.a.neighbor.s.phone.number",
                        "x14a.were..you.a.tubura.client.17a.", "x14b.are.you.a.tubura.client.17b.","x14c.are.you.a.tubura.client.in.18a.")], by=c("sample_id"= "x.form.sample_id"))
attritionTab <- attritionTab[,c(4,1,2,3,5,6, 7:13)]
#length(attritionTab$sample_id)==length(unique(attritionTab$sample_id))
# load data from Eric J on 9/11 - combine my missingn with those without a sample and update the googlesheet
ejDat1 <- read_xlsx("attrition table2017 09 11_EJ.xlsx", sheet=1) %>% 
  dplyr::select(sample_id, `sample collected (from tracker)?`, `reason (from tracker)`) %>%
  rename(sample_collected = `sample collected (from tracker)?`,
         reason = `reason (from tracker)`)
ejDat2 <- read_xlsx("attrition table2017 09 11_EJ.xlsx", sheet=2) %>% 
  dplyr::select(sample_id, `sample collected?`, reason) %>%
  rename(sample_collected = `sample collected?`) %>%
  rbind(., ejDat1)
#length(ejDat2$sample_id)==length(unique(ejDat$sample_id)) # duplicates in the missing data
# report missing values in the duplicates
dups <- ejDat2[duplicated(ejDat2$sample_id), "sample_id"] %>% 
  filter(!is.na(sample_id))
# show all the farmers for which we have multiple reasons listed:
# ejDat2 %>%
#   filter(ejDat2$sample_id %in% dups$sample_id) %>%
#   arrange(sample_id) %>%
#   kable(., format='markdown')

Eric, there isn’t clarity in Jeannette’s form about what has and has not been collected. Can she make a master database instead of two separate ones? Add a second column if you want to indicate the issue. For the time being I’m not going to add this into the rwR2Attrition google sheet until we have a definitive answer on what the status is.

# now put this information with the attrition Tab
#attritionTab <- left_join(attritionTab, ejDat2, by="sample_id")
  
write.csv(attritionTab, file=paste0("attritionTabs/attrition table", format(Sys.time(), '%Y %m %d'), ".csv"), row.names=F)
# also update a googlesheet to make collaborating on this possible:
library(googlesheets)

package ‘googlesheets’ was built under R version 3.3.2

# first uploading of the data
# test <- gs_upload(file=paste0("attritionTabs/attrition table", format(Sys.time(), '%Y %m %d'), ".csv"), "rwR2Attrition", overwrite=T)
# now I want to only edit certain rows:
# test <- test %>% 
#   gs_edit_cells(input = attritionTab$found,
#                 anchor = "F2", byrow=FALSE)
# 
# # bring in info from M&E team, merge reasons with current table and only show the farmers for which we are still missing an explanation
# 
# test <- read_xlsx("Farmer not find for SHS survey 7.9.2017.xlsx", sheet=2) %>%
#   rename(sample_id = `Soil ID`) %>%
#   mutate(sample_id = tolower(sample_id))
# table(test$sample_id %in% attritionTab$sample_id) # do they appear among the missing?
# table(test$sample_id %in% subset(fieldDat, fieldDat$season=="15b")$sample_id) # they are farmers but I've found them
  # dplyr::select(`Reason not found`, `Reason not found other`, District, Cell, Village, `Cell field`, `Respondent name`, `Farmer tel`, `Respondent tel`, `Neighbor tel`, sample_id) %>%
  # left_join(., attritionTab, by="sample_id") %>%
  # as.data.frame()
# find the farmer name in the original baseline data?
datatable(attritionTab)

5 Data reality check

The variable names are not great. I think it’s due to the CommCare API export. I’m going to see if there’s an easier way to have uesable variable names. I’ve creaetd a CC export titled “M&E - Soil Health Study - 17B Ubutaka (Soil)” on August 8th. I’m only using it to get more usable variable names quickly. Ideally there’d be away to get that info directly from CommCare.

varNames <- read_csv("M&E - Soil Health Study - 17B Ubutaka (Soil) (2017-08-04) 2017-08-04.csv") %>% 
  setNames(gsub("form.", "", names(.))) %>%
  setNames(gsub("farmer.", "", names(.))) %>%
  setNames(gsub("prim_17a_.", "", names(.))) %>%
  setNames(gsub("sec_17a_.", "", names(.))) %>%
  setNames(gsub("prim_17b_.", "", names(.))) %>%
  setNames(gsub("sec_17b_.", "", names(.))) %>%
  setNames(gsub("ammend_17a_.", "", names(.))) %>%
  setNames(gsub("ammend_17b_.", "", names(.))) %>% 
  as.data.frame()

Parsed with column specification:

numVars <- names(yt)[sapply(yt, function(x){

})]

Basic cleaning of known issues like enumerator codes for DK, NWR, etc.

enumVals <- c(-88,-85, -99, -9)
yt[,numVars] <- sapply(numVars, function(y){
  yt[,y] <- enumClean(yt,y, enumVals)
  yt[,y] <- as.numeric(yt[,y])
})
